Dear Bradley, Thank you for your request. The presented objects are two lamps made in the 20th century on gas-driven the other is a petrol lamp. One is stamped "Yale Style Light Co Chicago". The second lamp has an unreadable company name on its top. Both lamps are in very bad condition. An estimation would be under 5 USD. This estimation is based on actual recent past recorded auction sales of comparables. Retail "asking prices" can be higher and vary. With best regards, Georg
